Suzuki® LTZ 400

The Suzuki LT-Z 400 is available as a Slip-On or Full System in the Performance and Competition exhaust. The Performance Series Slip-on system picks up roughly 10-15% more horse power and torque throughout the power curve. The HMF system weighs substantially less than the stock muffler, so you'll see an overall weight drop. The Performance exhaust will increase sound levels approximately 4-6 decibels above the stock muffler, but the Competition Inserts and HMF Quiet Core insert can lower that 2-4dB.
